Re: Lets hope
I don't think the disapproval is specifically about machine learning being used on health data; that's been done on anonymized data for years by academic and industry researchers, and is likely to continue. I believe the complaint is about google, which has not before proven itself knowledgable about health, as this isn't much related to their standard business model, but has proven itself to not be great at keeping any data private, even data that citizens and governments believe should be more private than usual.
